*1 Although the POWER LED turns on in red for a moment immediately after the power supply is turned on or off,
redundant power supply modules is not faulty.
● Q64RP automatically switches the input range 100/200VAC.
Therefore, it cannot be used in the intermediate voltage (133 to 169VAC).
The CPU module may not work normally if the above intermediate voltage is applied.
● Supply power to redundant power supply modules from separate power sources (a redundant power supply system).
● Individually ground the LG and FG terminals with a ground resistance of 100  or less.

On (green): Normal operation (5V DC output, momentary power failure of 10ms or less)
On (red):
DC power is input but the Q63RP is faulty. (5V DC error, overload, or internal circuit failure)
Off: DC power not input, blown fuse, power failure (including momentary power failure of 10ms or more)
On (green): Normal (5V DC output, momentary power failure within 20ms)
On (red):
AC power supply is on but Q64RPN, or Q64RP is out of order.
(5V DC error, overload, or internal circuit failure)
Off: AC power supply is not on, blown fuse, power failure (including momentary power failure of 20ms or more)
<When power supply is mounted on redundant power main base unit (Q3RB)>
• Turns on when the system on the redundant power main base unit operates normally.
• Turns off (open) when the Q63RP fails, the DC power supply is not input, a CPU module stop error (including
a reset) occurs, or the fuse is blown.
• Turns off (open) when a stop error occurs in any of the CPU modules in a multiple CPU system.
<When power supply is mounted on redundant power extension base unit (Q6RB) or redundant type
extension base unit (Q6WRB)>
• Turns on when the Q63RP operates normally.
• Turns off (open) when the Q63RP fails, the DC power supply is not input, or the fuse is blown.
Ground terminal connected to the shield pattern of the printed circuit board.
Grounding for the power supply filter. The potential of AC input (Q64RPN, or Q64RP) terminal is 1/2 of the input
voltage.
Connect direct current of 24 VDC with the power input terminal.
Power input terminals for Q64RPN and connected to a 100VAC to 200VAC power supply.
Power input terminals for Q64RP and connected to a 100VAC/200VAC power supply.
M3.5 × 7 screw
Protective cover of the terminal block
Screw hole for securing a module to the base unit.
M3 × 12 screw (user-prepared) (Tightening torque : 0.36 to 0.48N•m)
Used to mount a module on the base unit.
